Bassin des constrictives is an interactive installation playing with the concept of psycho-phonetic synaesthesia. Norbert Godon and me made a huge review on the literature about synaesthesia. Especially on the point of view of speech. We tried to illustrate some of our findings into this installation that proposes to the audience to activate a ferrofluid with the sound of the voice.

First, we worked on a constrictive recognition system able to discriminate fricatives (sibilants and Palato-alveolar fricatives) from other sounds and to estimate the degree of constriction in real time. Then we mapped this degree of constriction to an magnetic field using an electromagnet. Finally, the electromagnet excited a ferrofluid making nice little spades, the number of which depends of the degree of constriction.
